Scientists Identify Two of the World’s Noisiest Birds – and They’re as Loud as a Jackhammer
Researchers measured 123 species and found the bare-throated bellbird and red-legged seriema both top 120 decibels.
- On Tuesday, University of Massachusetts Amherst researchers published a study in the journal Evolution identifying the bare-throated bellbird and red-legged seriema as new contenders for the world's loudest birds, both exceeding 120 decibels.
- Biologist Jeff Podos and his former graduate student João Menezes utilized laser range finders to overcome field measurement challenges that previously limited amplitude data collection on bird vocalizations.
- Researchers discovered a 58-decibel variability in calls, ranging from hummingbirds at 64 decibels to birds exceeding 120 decibels. "Bigger birds have bulkier muscles," Menezes said, noting that broader mouths allow more energy to radiate into the environment.
- The strictly monogamous red-legged seriema confounded theories predicting loudness correlates with polygamy. "It's a super open-habitat bird," Menezes added, indicating evolutionary reasons for such extreme vocalizations remain mysterious.
- Mass Audubon ornithologist Nathan Senner called the findings "remarkable," stating that understanding these evolutionary behaviors could lead to better protections. Researchers anticipate discovering even louder birds as fieldwork continues on a tiny fraction of species.
